Reviewed October 19, 2026 ## Why Slack eats your typing time The problem with Slack is not one long document. It is volume. - Dozens of short replies. Each one is only two or three sentences, but you write them all day, and each one means stopping what you were doing. - Tone matters more than length. A rushed one-liner can read as curt. Writing a friendlier version takes extra time you don't feel you have. - Explanations get cut short. When someone asks "why did we change this?", the full answer is easier to say than to type, so people often type a vague one and get follow-up questions. - Mixed-language teams. If teammates work in different languages, you may write the message twice or run it through a separate translator. You already know what you want to say. Just say it. ## How to dictate in Slack with SayDart in 3 steps Slack is a stream of small writing jobs: a quick answer in a thread, a status update in a channel, a careful DM to a teammate who is stuck. SayDart lets you speak those messages into the Slack message box and review them before you press Enter. SayDart is voice typing for Windows and Mac (beta). It works right in Slack, desktop or browser, with no Slack app to install and nothing for your admin to approve. 1. Click the message box. Open the channel, thread or DM in Slack and put your cursor in the message field. 2. Hold the thought, press the shortcut, speak. Use your voice shortcut (Right Alt on Windows and Right Option on macOS). Stop recording when you finish. 3. Read it once, then send. SayDart inserts the text into the message box. Slack still waits for you to press Enter, so you can fix a word or add an emoji first. Tip: for thread replies, start by naming who and what you are answering. "Maya, on the release date question..." gives the reply context without extra typing. ## SayDart features that fit Slack — Style for chat Pick Casual or Very casual in Style for team chat and Formal for customer channels. Auto cleanup takes out the "um"s either way. ## SayDart features that fit Slack — Snippets for things you paste every day Set a trigger word that expands into text you share often, such as your email address or a sign-off for external channels. ## SayDart features that fit Slack — Voice translation for cross-language channels Speak Chinese, post in English. Press your Translation shortcut, say the message in your language, and the translation lands in the box. ## SayDart features that fit Slack — Dictionary for teammates and tools Add colleagues' names, channel jargon and internal tool names to your Dictionary so a quick reply doesn't need three corrections. ## SayDart features that fit Slack — History for the message you deleted by mistake If you clear the message box or switch channels before sending, open SayDart History, find the dictation and reuse it. ## Example: a status update in a channel You say: "Quick update on the login bug. We found it, it's the token refresh, fix is in review and should ship tomorrow morning. I'll post here when it's live." That goes into the message box as a tidy three-sentence update. You read it, press Enter, and get back to work. Writing longer messages to people outside Slack? The same habit works for voice typing in Gmail. For notes you want to keep, try voice typing in Notion. ## Pricing SayDart is free to start. Pro is unlimited for $12/month, billed yearly ($144), or $15 month to month. Prices exclude tax. ## Talk, don't type. Install SayDart, open your busiest channel and reply to the next three threads out loud. ## Discord and Microsoft Teams: same habit, different apps The Slack habit transfers to Discord and Microsoft Teams: click the message box, hold SayDart shortcut (Right Alt on Windows, Right Option on Mac), speak, then review mentions and links before you send. Focus the composer first — Win+H and SayDart both need an active text field. Add server names, @handles, channel names and project jargon to the SayDart dictionary so Discord and Teams replies stay consistent with your Slack spelling. SayDart is not a bot inside Discord or Teams; it types where your cursor is. ## Related - [Voice typing for Notion](https://saydart.com/workflows/notion/) - [Voice typing for Gmail](https://saydart.com/workflows/gmail/) - [Dictation for ChatGPT](https://saydart.com/workflows/chatgpt/) - [SayDart pricing](https://saydart.com/pricing/) - [Download SayDart](https://saydart.com/download/) ## FAQ ### Can I use dictation in Slack with SayDart? Yes. Click the Slack message box, press Right Alt and talk. Works in the Slack app and the browser, on Windows and Mac. ### Do I need a Slack admin to approve SayDart? No. SayDart is not installed into your Slack workspace.

No. You review the draft in Slack and press Enter yourself when you are ready. ### Can I make dictated Slack messages sound casual? In Style > Text, Casual or Very casual keeps capitalization and punctuation light for chat, while Formal uses full capitalization and punctuation. Review the wording and tone yourself. In Style > Cleanup, choose Original to keep your words as spoken. ### Can I write a Slack message in another language by voice? Yes. Choose a target language in Settings > Voice & translation > Translate to and use Translation. You can set its shortcut in Settings > Shortcuts and review the result before sending.
